For example. "Cancer prevention" and "anti-aging" are eternal topics in health classes. There is nothing wrong with this, but the cognition of "cancer prevention and anti-aging" instilled by "tutors" and formed by "medical staff" is wrong, that is, treating cancer as a terminal disease and aging as a disease.
Isn't cancer a terminal disease? The idea that cancer equals death was thirty or forty years ago, but now many middle-aged and elderly people's understanding of diseases is mostly the knowledge reserve of that era. Professor Zhi, a famous lung cancer expert, once said that it was empty talk to say that "cancer is a chronic disease" 40 years ago, but today, especially with targeted drugs, living with cancer has become the norm, and "cancer is just a chronic disease" is becoming common sense. Although many cancers cannot be cured at present, they can be effectively controlled to prevent development or recurrence. Just like hypertension and diabetes, it can't be cured, but it can be completely controlled.
